New technology of hydrogen production from natural gas in natural gas hydrogen production plant
Hydrogen production by adiabatic conversion of natural gas in small-scale on-site hydrogen production in hydrogenation stations can better reflect the characteristics of its strong production capacity. The new process has the advantages of short process and simple operation unit, which can significantly reduce the investment and hydrogen production cost of small-scale on-site hydrogen production equipment. The following natural gas hydrogen production device-Suzhou Jiarui gas to introduce the new technology of natural gas hydrogen production : Adiabatic conversion of natural gas to hydrogen. The most prominent feature of this technology is that most of the raw material reactions are essentially partial oxidation reactions, and the rate-controlling step has become a fast partial oxidation reaction, which greatly improves the production capacity of natural gas hydrogen production units. The process of hydrogen production by adiabatic conversion of natural gas uses cheap air as oxygen source. The designed reactor with oxygen distributor can solve the hot issues of catalyst bed and the reasonable distribution of energy. The reaction stability of catalytic materials is also greatly improved due to the decrease of hot spots in the bed.

Partial oxidation of natural gas to produce hydrogen. Compared with the traditional steam reforming method, the process of catalytic partial oxidation of natural gas to syngas has low energy consumption and uses extremely cheap refractory materials to stack the reactor. However, the catalytic partial oxidation of natural gas to hydrogen increases the cost of expensive air separation plant investment and oxygen production due to the large amount of pure oxygen. The high temperature inorganic ceramic oxygen permeable membrane is used as a reactor for the catalytic partial oxidation of natural gas, and the cheap oxygen production is combined with the catalytic partial oxidation of natural gas to produce hydrogen at the same time. The preliminary technical and economic evaluation results show that compared with the conventional production process, the unit investment will be reduced by about 25-30 %, and the production cost will be reduced by 30-50 %.
Hydrogen production by high temperature cracking of natural gas. Pyrolysis of natural gas at high temperature to produce hydrogen is a process in which natural gas is decomposed into hydrogen and carbon by high temperature catalysis. Because it does not produce carbon dioxide, it is considered to be a transitional process between fossil fuels and renewable energy. In Liaohe Oilfield, a lot of research work has been carried out on hydrogen production from high temperature catalytic cracking of natural gas. The carbon produced can have specific important uses and broad market prospects.
Hydrogen production by autothermal reforming of natural gas. Compared with the reforming process, the process changes the external heating to self-heating, and the utilization of reaction heat is more reasonable. The principle is that the exothermic natural gas combustion reaction and the strongly endothermic natural gas steam reforming reaction are coupled in the reactor, and the reaction system itself can achieve self-heating. In addition, due to the strong exothermic reaction and strong endothermic reaction in the autothermal reforming reactor are carried out step by step, the reactor still needs high temperature resistant stainless steel pipe as the reactor, which makes the natural gas autothermal reforming reaction process have the disadvantages of high investment and low production capacity.
